She can sell out an item in minutes, and her outfits routinely create global sensations.
She’s not alone.
Her sister,Pippa Middleton, has the same knack for fashion.

In fact, the sisters often seem to inspire each other.
We’ve seen countless occasions in which they copy each other’s looks in classic sibling style.
However, there are slight differences.

Personal stylist Melissa Lund toldDaily Express, “Kate and Pippa are both classic dressers.
I’d say that Pippa’s style often appears sportier while Kate’s is more dramatic.”
Pippa’s looks, in contrast, aren’t as heavily scrutinized.

Sometimes, though, they look so similar that we are forced to do a double-take.
We’ve seen her wear dresses by this designer numerous times.
Pippa Middleton, like her sister, is also a fan of Alessandra Rich.

The dress also featured a high neckline and long sleeves.
“It is good to be a bit naughty.”
Eventually, Catherine phased this out and opted for softer eye makeup, which has been a great move.

Although Catherine has changed up her routine,Pippa continuesto favor darker and heavier liner.
She went monochromatic with burgundy pumps by Gianvito Rossi, burgundy gloves, and a matching clutch.
Pippa arrived at the event wearing a coat by Karen Millen that was virtually the same hue.

However, Pippa’s look featured a black leather belt and black buttons.
She wore brown boots and accessorized with a brown clutch.
Both Pippa and Catherine wore their hair in loose, long curls, looking much like twins.

Interestingly, Zara Phillips also wore a long burgundy coat to the event.
Was there some text thread between the three women to coordinate?
This was, as she explained, the reason for her neutral palette as a royal.

She wore a yellow lace dress by one of her favorite designers, Jenny Packham.
She paired the dress with oatmeal colored wedges by Monsoon and a similar toned clutch.
Catherine’s look was cheerful and colorful.

The general vibe was also more playful, as she sported a shorter haircut too.
Pippa Middleton wore a very similar outfit a few years prior.
She’s worn that particular style so many times that it’s almost become her official uniform.

However, she wasn’t the only royal to embrace the trend Princess Diana popularized the look.
At the christening of Princess Charlotte in 2015, Pippa and Catherine looked like twins in their coordinating outfits.
Pippa chose a cream dress by Emilia Wickstead and paired the look with a cream-colored fascinator.

Meanwhile, Catherine wore a cream coat dress by Alexander McQueen with a matching fascinator.
Both sisters wore nude pumps.
Catherine ended up loving her coat dress so much that she’s recycled it many times since.

She paired the gown with a gold clutch and gold heels.
It certainly goes to show the different protocols for royal women.
The sisters have also opted for red dresses in more casual prefs, too.

A few years later, Pippa was again spotted running errands in blue denim skinny jeans.
The Middleton sisters aren’t retiring this look anytime soon.
Catherine and Pippa have also rocked colorful skinny jeans coral in particular.

It was Pippa who led the way with this look.
In January 2012, Pippa paired coral skinny jeans with a black blazer and boots.
Catherine kept the look sporty with a grey hoodie and grey sneakers.
That’s some serious sway!
In fact, Princess Catherine has been rocking one for nearly two decades.
In 2013, Pippa Middleton showed up at the Cheltenham Festival twinning with Catherine’s previous look.
She wore a large fur hat and a yellow coat by Katherine Hooker.
Pippa, however, hasn’t rocked the look as many times as her older sister.
In 2018, Catherine wore the Lacorine hat while visiting Norway with Prince William.
At Wimbledon in 2017, Pippa donned a pink lace Self-Portrait dress.
She paired the look with grey heels and oversized sunglasses, and swept her hair back into a ponytail.
Considering the nature of the event, Pippa did a great job pairing sophisticated style with sporty elements.
Catherine has also worn Self-Portrait ensembles on a few occasions.
The dress featured architectured lace on the top and a thigh-high slit.
She paired the look with a red brooch, red pumps, and a red clutch.
In April 2022, while touring the Caribbean, Catherine wore a flowy mint green dress by Self-Portrait.
The dress was midi-length with a bustier-like top and puffed short sleeves.
The sisters frequently lean into plaid during the winter months.
A source toldVanity Fair, “The Queen isn’t a fan of wedged shoes.
She really doesn’t like them and it’s well known among the women in the family.”
Nevertheless, Catherine continues to wear espadrilles, favoring brands like Castaner Carina.
Thankfully for Pippa, her love of espadrilles has never angered the queen.
She’s also sported the shoe with skinny jeans another go-to item in her and her sister’s wardrobes.
Striped shirts for the Middleton sisters
The Middleton sisters know how to rock a striped top.
We’ve seen Catherine in a navy and white striped top several times.
In fact, according to theDaily Mail, Catherine owns three different versions of the classic Breton shirt.
“A stripe is a brilliant way of making an understated statement.”
She kept jewelry to a minimum, wearing simple, gold hoops.
She paired the look with nude heels by Gianvito Rossi.
The event marked one of the last royal engagements that Catherine performed before giving birth to her son.
Her sister, Pippa Middleton, also favored green during her pregnancy.
In addition to wearing green during their respective pregnancies, Catherine and Pippa also favored Seraphine maternity clothing.
